Kate and Camilla definitely colour-coordinate their clothes. I mean, Trooping the Colour blue might have been coincidence, but today's cream (and nude shoes) just cannot be.
Love what all three ladies (Camilla, Kate and Sophie) are wearing, and the Duchess of Gloucester looks very nice too.

WOW! they all look very pretty. IMO one of the best outfits Kate has worn, it makes her look fuller, not so incredibly skinny. Good Job. Duchess of Cornwall and Countess look amazing also. All three really hit the right note.

What exactly did the DoCo say to the other two that put that expression on their faces lol.

Just an off the wall observation here that may put some previous discussions into perspective. Here we see Camilla and Kate seated facing forwards in the carriage while their husbands face the rear. The chivalrous thing for Knights to do I think.

Why has Harry not yet been named a knight of the garter? Surely his service in Afganistan would qualify, in addition to his own charities. I also wonder why he doesn't ride in the trooping the color?

There may be various reasons.
- His service in Afghanistan and charities, while highly commendable, doesn't automatically earn him the right to be invested as Knight of the Garter.
- Harry is still too young. While Prince Charles and Prince William both got the honour when they were of similar age, they are future Kings; Harry is not.
- The Queen may deliberately not want to invest Prince Harry, so that when time comes, King Charles has the chance to bestow the honour on at least one of his sons.

QMII, like most European monarchs in a member of the order but they rarely if ever attend. I think the last time she and the others attended was at the Golden Jubilee year when QEII hosted a party at Windsor for European monarchs. A few also stayed on the attend Ascot.
